Cee-lo may be better known to some as the soulful singing half of Gnarls Barkley, with hits like "Crazy." He has a voice bigger than his body, and this summer came out with a great break-up anthem which we can't fully print on this website. His song "F*** You" — or "Forget You," if you prefer the radio edit — is his ode to a gold-digging object of his affection.
